Our Strength - Design, erection, quality control, erection

(supervision), cold trial, hot trial, full fledged production of Ferroalloys (complete) and steel plants (as per listed equipments).

This we do on turn key basis

As we do commissioning ourselves, we continuously improve ourdesign and incorporate all the view points (after proper analysis)

of experienced operators.

Working philosophy: MECHANICAL

We do the complete engineering of mechanical equipments with

3D software. With this software we achieve following :

We check the complete assembly of the furnace. We check and

correct the interferences in the matching part.

Design optimisation and finite elements determination.

Optimum water requirement (on the basis of surface area

exposed to heat zone)

We get the CG (centre of gravity) and accurate weight of the

equipment.

Erection time is reduced drastically. In House Design Of ElectrodeHolder in 3 D Software

ELECTRICAL :

We do the complete electrical engineering with latest software having capabilities of integrating all electrical

activities, single line diagram,bom, electrical symbols.This has got advantages over normal cad design.

Fast, Easy & precise project configuration.

Highest level of project documentation quality due to Standardization.

Maximum Design flexibility. Panel Mounting, SLD

Accurate & logical representation of all connected device through any bus topology, plc & single- line diagram.

Eliminate error prone manual data entry of BOM, Interfacing, Assembly report.

For the Arc furnace electrical design we do following calculations:

Furnace impedance (based on the charge mix)

Transformer voltage and impedance selection (on K value)

Transformer voltage selection is done on the basis of types of Ferro alloys. The design incorporates PCD changing

provision and enhanced range of transformer voltages, if product change is envisaged.

We incorporate arc furnace technology into submerged arc furnace. This helps the operator run the furnace in

controlled and easy way. Safety features, especially in Bellow type pressure rings and close/semi close roofs are

provided. This is based on the Arc furnaces technology.

Project control and monitoring:

We prepare the complete project

planning with latest softwares. All

activities are based on our past

experience, meticulously recorded by

us in the previous projects

This project planning is further

subdivided into detailed planning

area wise.

This helps to meet the target dates,

very closely.

Vaibhav Furnaces Special Design Features

Electrode Holder: This robust design of electrode holder give better result inminimizing energy consumption, low maintenance & safe operation offurnace.

Main Components Of System

Fail Safe hydraulic operated slipping & electrode regulation device.

1500 v Electrical Insulation Electrode casing welding in running furnace

Controlled Electrode Slipping in full load

Proper Electrode baking for current transfer

Electrodes : we Design Holder for pre-baked & self baked electrode

Self baking electrode : It reduce the production cost in Ferro alloy productFe-Si, Fe-Cr, CaC2.

Cooling & Refractory Lining Concept: We Design the cooling part &refractory to ensure long life, safe operation & Minimum heat loss ofcooling equipment.

Hydraulic power pack

Tap hole cooling

Electrical Aspects: high current electric component are Heart of Furnace & critical for energy

optimization and optimum production.

Vaibhav Furnaces design very carefully to minimize the power loss. We consider following during detail

engineering :

Voltage & Impedance Of transformer

Reactance Of High current Bus tube/ Bar

Resistance Of charge K factor of the final products

Proper insulation on live part

Harmonic & PF correction

Layout of Bus bar, to suit the impedence

Proper selection of Electrode Diameter

Insulations to minimize magnetizing effect

It Give Benefit to Customer

Optimum Furnace operation

Minimized electric losses

Long life High current Electric supply system
